Education Secretary Arne Duncan has accepted an apology from the president of the Chicago Teachers Union for a joke she made about him having a lisp.
Karen Lewis said at a union event in Seattle last month that she could tell Duncan "went to a private school, because if he had gone to a public school, he would have had that lisp fixed." Her comments were caught on video.
Lewis said Monday she was wrong to make the joke and called Duncan to explain.
Education department spokesman Justin Hamilton said Tuesday that Duncan accepted her apology.
Duncan led Chicago's public schools before becoming education secretary. He has clashed with teachers' unions in Chicago and Washington over the expansion of non-union charter schools.
Chicago Public Schools officials declined to comment.
